There’s no such thing as a free lunch.

Brown County health officials have declared wind turbines a public health risk, but they haven’t determined how to put their declaration into action.

The county’s Health Board this month declared the Shirley Wind Farm operated by Duke Energy Renewables poses a health risk to its neighbors in the town of Glenmore. Three families have moved out of their homes rather than endure physical illness they blame on the low-frequency noise the wind turbines generate, according to Audrey Murphy, president of the board that oversees the Brown County Health Department.

“We struggled with this but just felt we needed to take some action to help these citizens,” Murphy said.
